Safety information
●Before mounting or operating the outboard
motor, read this entire manual. Reading it
should give you an understanding of the
motor and its operation
●Before operating the boat, read any own-
er’s or operator’s manuals supplied with it
and all labels. Be sure you understand each
item before operating.
●Do not overpower the boat with this out-
board motor. Overpowering the boat could
result in loss of control. The rated power of
the outboard should be equal to or less than
the rated horsepower capacity of the boat.
If the rated horsepower capacity of the boat
is unknown, consult the dealer or boat man-
ufacturer.
●Do not modify the outboard. Modifications
could make the motor unfit or unsafe to use.
●Never operate after drinking alcohol or tak-
ing drugs. About 50% of all boating fatalities
involve intoxication.
●Have an approved personal flotation device
(PFD) on board for every occupant. It is a
good idea to wear a PFD whenever boat-
ing. At a minimum, children and non-swim-
mers should always wear PFDs, and
everyone should wear PFDs when there
are potentially hazardous boating condi-
tions.
●Gasoline is highly flammable, and its va-
pors are flammable and explosive. Handle
and store gasoline carefully. Make sure
there are no gas fumes or leaking fuel be-
fore starting the engine.
●This product emits exhaust gases which
contain carbon monoxide, a colorless,
odorless gas which may cause brain dam-
age or death when inhaled. Symptoms in-
clude nausea, dizziness, and drowsiness.
Keep cockpit and cabin areas well ventilat-
ed. Avoid blocking exhaust outlets.
●Check throttle, shift, and steering for proper
operation before starting the engine.
●Attach the engine stop switch lanyard cord
to a secure place on your clothing, or your
arm or leg while operating. If you acciden-
tally leave the helm, the cord will pull from
the switch, stopping the engine.
●Know the marine laws and regulations
where you will be boating—and obey them.
For basic boating rules, see “Rules of the
road”on page 4.
●Stay informed about the weather. Check
weather forecasts before boating. Avoid
boating in hazardous weather.
●Tell someone where you are going: leave a
Float Plan with a responsible person. Be
sure to cancel the Float Plan when you re-
turn.
●Use common sense and good judgment
when boating. Know your abilities, and be
sure you understand how your boat han-

dles under the different boating conditions
you may encounter. Operate within your
limits, and the limits of your boat. Always
operate at safe speeds, and keep a careful
watch for obstacles and other traffic.
●Always watch carefully for swimmers during
the engine operation.
●Stay away from swimming areas.
●When a swimmer is in the water near you
shift into neutral and shut off the engine.

Basic boating rules (Rules of
the road)
Just as there are rules which apply when you
are driving on streets and high ways, there
are waterway rules which apply when you are
driving your boat. These rules are used inter-
nationally, and are also enforced by the Unit-
ed States Coast Guard and local agencies.
You should be aware of these rules, and fol-
low them whenever you encounter another
vessel on the water.
Several sets of rules prevail according to geo-
graphic location, but are all basically the same
as the International Rules of the Road. The
rules presented here in your Owner’s Manual
are condensed, and have been provided for
your convenience only. Consult your local
U.S. Coast Guard Auxiliary or Department of

Motor Vehicles for a complete set of rules
governing the waters in which you will be us-
ing your boat.
EMU25510
Steering and sailing rules and sound
signals
Whenever two vessels on the water meet one
another, one vessel has the right-of-way; it is
called the “stand-on”vessel. The vessel
which does not have the right-of-way is called
the “give-way”or “burdened”vessel. These
rules determine which vessel has the right-of-
way, and what each vessel should do.
Stand-on vessel
The vessel with the right-of-way has the duty
to continue its course and speed, except to
avoid an immediate collision. When you main-
tain your direction and speed, the other vessel
will be able to determine how best to avoid
you.
Give-way vessel
The vessel which does not have the right-of-
way has the duty to take positive and timely
action to stay out of the way of the Stand-On
vessel. Normally, you should not cross in front
of the vessel with the right-of-way. You should
slow down or change directions briefly and
pass behind the other vessel. You should al-
ways move in such a way that the operator of
the other vessel can see what you are doing.
“The general prudential rule”
This rule is called Rule 2 in the International
Rules and says,
“In obeying and construing these rules due re-
gard shall be had to all dangers of navigation
and collision, and to any special circumstanc-
es, which may render a departure from the
above rules necessary in order to avoid im-
mediate danger.”
In other words, follow the standard rules ex-
cept when a collision will occur unless both
vessels try to avoid each other. If that is the
case, both vessels become “Give-Way”ves-
sels.
EMU25520
Rules when encountering vessels
There are three main situations which you
may encounter with other vessels which could
lead to a collision unless the Steering Rules
are followed:
Meeting: (you are approaching another ves-
sel head-on)
Crossing: (you are traveling across the other
vessel’s path)
Overtaking: (you are passing or being
passed by another vessel)
In the following illustration, your boat is in the
center. You should give the right-of-way to
any vessels shown in white area (you are the
Give-Way vessel). Any vessels in the shaded
area must yield to you (they are the Give-Way
vessels). Both you and the meeting vessel
must alter course to avoid each other.
Meeting
If you are meeting another power vessel head
on, and are close enough to run the risk of col-
lision, neither of you has the right-of-way!
Both of you should alter course to avoid an ac-
cident. You should keep the other vessel on
63P10.book Page 5 Tuesday, May 13, 2003 10:23 AM

General information

your port (left) side. This rule doesn’t apply if
both of you will clear one another if you con-
tinue on your set course and speed.
Crossing
When two power driven vessels are crossing
each other’s path close enough to run the risk
of collision, the vessel which has the other on
the starboard (right) side must keep out of the
way of the other. If the other vessel is on your
right, you must keep out of its way; you are the
Give-Way vessel. If the other vessel is on
your port (left) side, remember that you
should maintain course and direction, provid-
ed the other vessel gives you the right-of-way
as it should.
Overtaking
If you are passing another vessel, you are the
“Give-Way”vessel. This means that the other
vessel is expected to maintain its course and
speed. You must stay out of its way until you
are clear of it. Likewise, if another vessel is
passing you, you should maintain your speed
and direction so that the other vessel can
steer itself around you.
EMU25530
Other special situations
There are three other rules you should be
aware of when driving your boat around other
vessels.
Narrow channels and bends
When navigating in narrow channels, you
should keep to the right when it is safe and
practical to do so. If the operator of a power-
driven vessel is preparing to go around a
bend that may obstruct the view of other water
vessels, the operator should sound a pro-
longed blast on the whistle (4 to 6 seconds). If
another vessel is around the bend, it too
should sound the whistle. Even if no reply is
heard, however, the vessel should still pro-
ceed around the bend with caution. If you nav-
igate such waters with your boat, you will
need to carry a portable air horn, available
from local marine supply stores.
Fishing vessel right-of-way
All vessels which are fishing with nets, lines or
trawls are considered to be “fishing vessels”
under the International Rules. Vessels with
trolling lines are not considered fishing ves-
sels. Fishing vessels have the right-of-way re-
gardless of position. Fishing vessels cannot,
however, impede the passage of other ves-
sels in narrow channels.
Sailing vessel right-of-way
Sailing vessels should normally be given the
right-of-way. The exceptions to this are:
1. When the sailing vessel is overtaking the
power-driven vessel, the power-driven
vessel has the right-of-way.
2. Sailing vessels should keep clear of any
fishing vessel.
63P10.book Page 6 Tuesday, May 13, 2003 10:23 AM

General information

3. In a narrow channel, a sailing vessel
should not hamper the safe passage of a
power-driven vessel which can navigate
only in such a channel.
Reading buoys and other markers
The waters of the United states are marked
for safe navigation by the lateral system of
buoyage. Simply put, buoys and markers
have an arrangement of shapes, colors, num-
bers and lights to show which side of the buoy
a boater should pass on when navigating in a
particular direction. The markings on these
buoys are oriented from the perspective of be-
ing entered from seaward (the boater is going
towards the port). This means that red buoys
are passed on the starboard (right) side when
proceeding from open water into port, and
black buoys are to port (left) side. When navi-
gating out of port, your position with respect to
the buoys should be reversed; red buoys
should be to port and black buoys to star-
board.
Many bodies of water used by boaters are en-
tirely within the boundaries of a particular
state. The Uniform State Waterway Marking
System has been devised for these waters.
This system uses buoys and signs with dis-
tinctive shapes and colors to show regulatory
or advisory information. These markers are
white with black letters and orange boarders.
They signify speed zones, restricted areas,
danger areas, and general information.
Remember, markings may vary by geograph-
ic location. Always consult local boating au-
thorities before driving your boat in unfamiliar
waters.

NOTE:
The engine cannot be started if battery volt-

EMU25740
Propeller selection
The performance of your outboard motor will
be critically affected by your choice of propel-
ler, as an incorrect choice could adversely af-
fect performance and could also seriously
damage the motor. Engine speed depends on
the propeller size and boat load. If engine
speed is too high or too low for good engine
performance, this will have an adverse effect
on the engine.
Yamaha outboard motors are fitted with pro-
pellers chosen to perform well over a range of
applications, but there may be uses where a
propeller with a different pitch would be more
appropriate. For a greater operating load, a
smaller-pitch propeller is more suitable as it
enables the correct engine speed to be main-
tained. Conversely, a larger-pitch propeller is
more suitable for a smaller operating load.
Yamaha dealers stock a range of propellers,
and can advise you and install a propeller on
your outboard that is best suited to your appli-
cation.
NOTE:
Select a propeller which will allow the engine
to reach the middle or upper half of the oper-
ating range at full throttle with the maximum
boat load. If operating conditions such as light
boat loads then allow the engine r/min to rise
above the maximum recommended range, re-
duce the throttle setting to maintain the en-
gine in the proper operating range.
For instructions on propeller removal and in-
stallation, see page 54.

EMU26190
Remote control lever
Moving the lever forward from the neutral po-
sition engages forward gear. Pulling the lever
back from neutral engages reverse. The en-
gine will continue to run at idle until the lever
is moved about 35°(a detent can be felt).
Moving the lever farther opens the throttle,
and the engine will begin to accelerate.

Neutral interlock trigger
To shift out of neutral, first pull the neutral in-
terlock trigger up.
EMU26210

EMU26230
Free accelerator
To open the throttle without shifting into either
forward or reverse, push the free accelerator
button and move the remote control lever.
NOTE:
●The free accelerator button can only be
used when the remote control lever is in the
neutral position.
●After the button is pushed, the throttle be-
gins to open after the remote control lever is
moved at least 35°.
●After using the free accelerator, return the
remote control lever to the neutral position.
The free accelerator button will return auto-
matically to its set position. The remote con-
trol will then engage forward and reverse
normally.
EMU25970
Throttle friction adjuster
A friction device provides adjustable resis-
tance to movement of the throttle grip or the
remote control lever, and can be set accord-
ing to operator preference.
To increase resistance, turn the adjuster
clockwise. To decrease resistance, turn the
adjuster counterclockwise.
WARNING
EWM00030
Do not overtighten the friction adjuster. If
there is too much resistance, it could be
difficult to move throttle lever or grip,
which could result in an accident.
